, Beit known that I, ALFREn-SCHALEK, a citizen of the UnitedStates ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented-certain new and useful Improvements inPhotographic-Film Holders, of which the following is a specification.

l'This invention relatesto that class of holders'employed for holdingphotographic iilrns duri-ng the developing and fixing processes,

and has for its object to provide a simple and effective structuralformation and combinav4 tion of parts wherewith the iilmis held in astraight and flat condition, 'and in a positive and 'eiiicient manner'during the exposure to chemical treatment in the photographic baths,all as will hereinafter more fully ap pear. v i

In the accompanying drawingszr-v liigure 1 is a perspective View of theholder in a partially opened condition Fig. 2 is a l'ront elevvation of'the holder.

Fig. 3 is an enlarged detail section on line 1f-90, Fig. 2.

' together at one end.

Referring tothe drawings. l and! are counterpart [lat rectangularholding vtrames vol rigid sheet metal or othei' equivalent mate- -rlaladapted to resistl the corrosive action of the develo )iner and ixinirbaths. h h
